Abstract / Synopsis

The effect of two different initial culture pHs on growth of six stranis of
rhizob a (TAL 102, was first studeid by using shake flask expermient. Only B radyrhizobium TAL
102 grew better at pH 4.5 compared to 6. and this strain was chosen as an
acid -to lerantrhizobia. This result is in agreement with the result of the
experiment using the fermenter in which the culture pH was controlled at a
constant value of 4.5 and 6.5 throughout the cultivation. However, parameters such as maximum cell concentration attained (Xm) differed
significantly.
